This invention relates to a wringer for collapsible tubes.

An object is to devise a wringer for collapsible tubes on the principle of a sprung spring clip with two closed spring loop ends.

I attain this object by a device illustrated in the accompanying drawing, in which Figure 1 is a side view of a blank from which the device is made;

Figure 2 is a top view of the device;

Figure 3 is a side view of the device;

Figure 4 is a right cross-sectional view along the plane A-A, Figure 3; and

Figure 5 is a right cross-sectional view on the plane BB, Figure 3.

In Figure l is shown a blank; consistin of a short length of tubing made of spring temperable stainless steel by cold extrusion. The cold extrusion process spring tempers the tubing. A special heat treatment for spring tempering the tubing is not necessary. The blank consists of two intermediate flat parallel portions 2 and 6, two integral cylindrical spring portions 3 and l, and four integral lever portions I, I, 3 and 5. While the device is bein made, the two intermediate portions 2 and 6 are pried apart and then each intermediate portion 2 and 6 is form stamped by a formin punch and die to form the jaws it and i5 trough-like in cross section, the ends of the troughs being numbered [ti and i6, and also the four stops 9, l3, ll and i2 as shown in Figures 2, 3, 4 and 5 which are punched out laterally from the troughs forming recesses with inner walls H. The resulting jaws l and i are released from the prying action whereupon the jaws Hi and is spring strongly against each other. There is a tendency for jaws Iii and E5 to cross each other due to the tension of the two cylindrical sprin portions 8 and d but this tendency is counteracted by the four stops t, it,

H and 52 which stops thus retain transversely jaws l8 and !5 in their opposed positions in relation to each other. The jaws H) and it have inner contacting wringing surfaces which contact along a common line It as shown in Figure 3. The pair of stops 9 and I3 are spaced apart from the pair of stops II and I2 a distance exceeding the width of the wrung rear portion of a collapsible tube intended to be wrung by the device and thus the two pairs of stops guide a collapsible tube which may be interposed between jaws ill and 15 between the two pairs of stops. The lever portions I, l, 3 and 5 cooperate with the spring portions 8 and 4 serving as fulcrums to pry apart jaws ill and [5 while the pair of lever portions l and 1 are being pressed together simultaneously with the pressing together of the pair of lever portions 3 and 5. In an alternative form of the device, the two bottom lever portions 7 and 5 may be omitted. I'o pry apart the jaws it and I5 with only the two top lever portions l and 3 the wringer is to be laid on a table with spring portions 8 and ll resting on the table and then the two top lever portions I and 3 are to be pressed down simultaneously by two fingers of ones hand.

In use the device is slid forwardly along a collapsible tube interposed between jaws it) and i5 toward the discharge orifice of the collapsible tube from time to time as the contents of the collapsible tube are exhausted by use. The device is not intended to be used to dispense the contents of a collapsible tube. Ones fingers are intended to be used for dispensing the contents of a collapsible tube. The ends of the spring portions 8 and 4 are sprun resiliently apart and exert a sufficiently strong spring tension on jaws it and i5 to effectively wring a collapsible tube interposed between the contacting opposed surfaces of jaws Ill and 55 while the device is being slid toward the discharge orifice of a collapsible tube up to the rear of the remaining contents of the collapsible tube and serve as a back stop for the remaining contents of the collapsible tube to prevent the remaining contents from being pushed back.

The prying leverage action of the lever portions i, l, 3 and 5 is similar to the prying, leverage action of spring clips which are provided with one or two prying levers.

This device can be adapted for use as a buckle for belts and straps.

The lever portions I, I, 3, and ii should be extremely thin, extremely flexible and resilient at their edges adjacent to jaws It and 15; the remainder of the lever portions l, i, 3, and 5 should be comparatively thick and rigid.

I claim:

l. A wringer for collapsible tubes comprising a pair of oppositely disposed contacting rectilinear jaws joined at one end by a spring loop and joined at the other end by another spring loop and pressing strongly against each other by the tension of said spring loops, means to retain transversely said jaws in their opposed positions in relation to each other, and a pair of fixed levers, each lever located near each end of a said jaw, said levers cooperating with said spring loops serving as fulcrums to pry apart said jaws.

2. A wringer for collapsible tubes comprising a pair of oppositely disposed contacting rectilinear jaws joined at one end by a spring loop and joined at the other end by another spring loop and pressing strongly against each other by the tension of said spring loops, and a pair of fixed levers, each lever located near each end of a said jaw, said levers cooperating with said spring loops serving as fulcrmns to pry apart said jaws.

3. A wringer for collapsible tubes comprising a pair of oppositely disposed contacting rectilinear jaws joined at one end by a spring loop and joined at the other end by another spring 100p and pressing strongly against each other by the tension of said spring loops, and means to retain transversely said jaws in their opposed positions in relation to each other.

4. A wringer for collapsible tubes comprising a pair of oppositely disposed contacting rectilinear jaws joined at one end by a spring loop and joined at the other end by another spring loop and pressing strongly against each other by the tension of said spring loops, and a pair of fixed stops, each stop located near each end of the contacting portions of said pair of jaws to retain a collapsible tube within said contacting portions of said pair of jaws.

5. A wringer for collapsible tubes comprising a pair of oppositely disposed rectilinear jaws joined at one end by a spring loop and joined at the other end by another spring loop, and a pair of fixed levers, each lever located near each end of a said jaw, said levers cooperating with said spring loops serving as fulcrums to pry apart said jaws.

6. A wringer for collapsible tubes comprising a pair of oppositely disposed contacting rectilinear jaws joined at one end by a sprin loop and joined at the other end by another spring loop and pressing strongly against each other by the tension of said spring loops, and means to retain transversely said jaws in their opposed positions in relation to each other, said means comprising two pairs of fixed stops, each pair of stops located near each end of said pair of jaws, each stop of each pair of stops located at opposite sides of said pair of jaws.

'7. A wringer for collapsible tubes comprising a pair of oppositely disposed contacting rectilinear elongate slender jaws joined at one end by a spring loop and joined at the other end by another spring loop and pressing strongly against each other by the tension of said spring loops, means to retain transversely said jaws in their opposed positions in relation to each other, a pair of fixed stops, each stop located near each end of the contacting portions of said pair or jaws to retain a collapsible tube within said contacting portions of said pair of jaws, and a pair of fixed levers, each lever located near each end of a said jaw, said pair of levers cooperating with said spring loops serving as fulcrums to pry apart said jaws, said wringer entirely constructed of one integral piece of metal from one integral blank.

8.
